<h3>Method Details</h3>
<div class="method">
    <code class="details" id="list">list(userId, pageToken=None, maxResults=None, startHistoryId=None, labelId=None)</code>
  <pre>Lists the history of all changes to the given mailbox. History results are returned in chronological order (increasing historyId).

Args:
  userId: string, The user's email address. The special value me can be used to indicate the authenticated user. (required)
  pageToken: string, Page token to retrieve a specific page of results in the list.
  maxResults: integer, The maximum number of history records to return.
  startHistoryId: string, Required. Returns history records after the specified startHistoryId. The supplied startHistoryId should be obtained from the historyId of a message, thread, or previous list response. History IDs increase chronologically but are not contiguous with random gaps in between valid IDs. Supplying an invalid or out of date startHistoryId typically returns an HTTP 404 error code. A historyId is typically valid for at least a week, but in some circumstances may be valid for only a few hours. If you receive an HTTP 404 error response, your application should perform a full sync. If you receive no nextPageToken in the response, there are no updates to retrieve and you can store the returned historyId for a future request.
  labelId: string, Only return messages with a label matching the ID.

Returns:
  An object of the form:

    {
    "nextPageToken": "A String", # Page token to retrieve the next page of results in the list.
    "historyId": "A String", # The ID of the mailbox's current history record.
    "history": [ # List of history records.

              ],
